An investigation of TCP security and performance issues when deployed in high-speed networks

As high-speed networks become more prevalent in modern communication infrastructures, the security and performance of the underlying transport protocols become increasingly important. A few particular problems arise when Transport Control Protocol (TCP), a crucial component of the internet, is implemented on high-speed networks. This study delves deeply into the performance and security concerns related to TCP in high-speed networks, including the effects of higher data rates and shorter round trip durations. It also suggests possible remedies that could lessen these risks. The study investigates the inefficiencies in TCP's congestion control algorithms, which are optimized for slower networks, when it comes to making the most use of available bandwidth in high-speed settings. It looks at the effects of being more susceptible to Distributed Denial of Service (DDoS) assaults, which have the ability to overload TCP connections and undermine their dependability. The paper examines current TCP variants and additions, such as TCP BBR and TCP SACK, which attempt to increase TCP's adaptability to high-speed network situations, in order to address these issues. It assesses how well these solutions work to mitigate the performance difficulties that have been identified and to sustain dependable and effective communication in high-speed contexts. The primary goals of the research are to improve our knowledge of TCP security and performance in high-speed networks and to aid in the development of more robust and secure communication protocols.
